Tried to load a WLMP to FB but would not accept format.  MS help said I needed to load newer Movie Maker which I did.  Instructions said to make movie and click on "F"link to share with FB.  Did that, got the sign on to FB menu, did that, and hit share button but have never seen it on FB.  Any ideas why?  File is not large only about 1.5 minutes long and 70Kb in size.
